spirvdis

spirvdis is a command-line utility used for disassembling SPIR-V bytecode. SPIR-V is an intermediate representation (IR) for graphics and compute shaders, commonly used in Vulkan, OpenGL, and OpenCL. The SPIR-V format is a binary representation, making it difficult for humans to read directly. spirvdis takes this binary SPIR-V code and translates it into a human-readable assembly-like text format.

This disassembly process is crucial for debugging shader code, understanding shader behavior, and analyzing shader compilation. Developers can use spirvdis to inspect the instructions generated by a compiler, identify potential performance bottlenecks, or verify the correctness of the shader's logic. The output of spirvdis typically shows each SPIR-V instruction with its corresponding opcode and operands.

spirvdis is often part of larger graphics development toolchains. Its primary function is to bridge the gap between the machine-readable binary SPIR-V and the human-understandable textual representation, facilitating a deeper understanding of shader programs.
